Migration

Setting up Channelize.io and migrating your users, messages & their relationships from your main application or existing chat application to Channelize.io services is very easy. This section will help you complete the migration quickly.

Export

The first step is downloading an export of your data from your main application or existing chat application. This process takes typically a few hours to a few days depending on the size of data you're exporting.

Import

Follow the below steps to import the downloaded export file:

Create a .zip file containing JSON files of the data exported. (Full file reference below).
Share the file with the Channelize Support team at support@channelize.io to import to your Channelize services.
Post validating the file, the Channelize support team will import the data and update you post data migration. Migration takes typically a few hours to a few days depending on the size of data you're exporting.

The .zip file which will contain the following JSON data files:

user.json - Data of users & their relationships with other users i.e friends list, following list and blocked lists.

conversation.json - Existing conversations in the Application.

message.json - Existing messages in the Application.

The structure of these JSON files is explained below. The .zip file should always have a customer.json file. The rest two JSON files are not mandatory. Find below the structure of created JSON files for data import:
